SOLDERING-IRON.

SPECEFCATION forming part of Letters Patent No. 680,519, dated August 13, 1901.

Application filed October 4, 1900. Serial No. 31,999. (N0 model.)

To @ZZ whom, my concern;

Be it known that I, GEORGE A. DENIS, a citizen of the United States, residing at Philaf delphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement in SolderingIrons, of which the following is a specification.

Myinvention relates to new and useful improvenients in soldering-irons of the class that are heated by gasolene and the like, and has for its object to provide a heating attachment to the soldering-iron that will give the greatest possible amount of heat at the proper point and having the mechanism so simple in construction and few in parts that the iron itself will not be cumbersome and will be neat in appearance.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claim.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a longitudinal section of the soldering-iron, the lower half of the reservoir and bulb being left in elevation; and Fig. 2 is a side view of the soldering-iron, the view being at right angles to Fig. l.

In carrying out iny invention as here embodied, A represents the reservoir, which is adapted to contain gasolene or other burning Huid. This reservoir A also serves for the handle of the soldering-iron. Leading from the inner end of the reservoir is a pipe B. This pipe B is joined at the point b with a filtering-cavity C. This cavity C is adapted to be filled with absorbent cotton or like material, (represented in the drawings at D.) This cotton is for the purpose of ltering the gasolene before it enters the burner.

Leading from each side of the filter C are pipes E. These pipes or ducts E enter the burner F at the pointf. Passing upward and into the burner through the stuffing-box F is a screw-rod G. This screw-rodG is th readed at the point g in the stufng-bozi. The opposite end of the burner from the stuffing-box is closed, except a small tapering opening F2, into which opening is adapted to lit the nee dle-point G', which is formed on the end of the screw-rod G, thus forming a needle-valve for controlling the How of gasolene and gas from the burner. The opposite end of the screw-rod G from the needle-point has located thereon means for operating the needle-valve, (here illustrated as a milled head G2.) The burner F enters a perforated pipe I-I. Secured upon the opposite end of this perforated pipe His the hollow shell I, upon which is Secured the soldering-iron proper, J, by means of bayonet-joints j. Located beneath the burner is a shallow pan or generating-cup K. This is secured to the burner at the point k.

The operation of my improvement is as follows: When it is desired to heat the iron, the needle-valve is opened, and then the bulb L, which communicates with the reservoir by means of the pipe l and check-valve, is compressedsufficiently to force a small quantity of gasolene through the burner, .which will flow through the tapering opening F2 into the perforated pipe II and from there through the sm all openings 72, into the generating-cup, where it will be lighted, and in burning will heat the burner, so as to generate gas, and when sufficient gas has been generated the iiow of the same will be regulated bythe needle-valve, and the flame will then iiow through the perforated pipe H up into the hollow shell I and soldering-iron proper, J. The cut-away portions t' in the shell I and the perforations .I in the soldering-iron .I will allow the excess heat to escape, as is understood is necessary in the proper heating of the iron. The perforations H in the pipe H furnish air for the proper burning of the iiame.

The advantages of my invention are that the burner is located such a distance from the handle or reservoir A that the heat will not be communicated to the handle, and the parts being few in number and all made interchangeable it would not easily get out of order and could be easily repaired if any portions were broken or damaged.

Of course I do not wish to be limited to the exact construction here shown, as slight modications might be made without departing from the spirit of my invention.

IOS

cular opening tting over the stuffing-box whereby the pan is suspended and suitable supports and connections for the head, as and l5 for the purpose described.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribng Witnesses.
